HP-IDE
HP-IDE was my development environment for the HP-48. I worked on it while I was at the University of Calgary .
An article in spanish was written about it, that a user was kind enough to send in:
I'm currently digging the source up off my backup CDs. My goal is to release it as open-source, but I've just got to get off my butt and get it up here.
